A poster of former premier Danny Williams has popped up along the busy thoroughfare outside the Confederation Building in St. John's.

The poster, which was also posted in Pippy Park, contains a photo of Williams laughing with the words "The Running Mouth."

It also has two emails attached at the bottom — donations@therunningmouth.ca and submissions@therunningmouth.ca.

It's unknown who is behind the poster.

A series of posters targeting Ball have been plastered on poles lining Prince Philip Parkway and in other parts of the city. That campaign was sparked by a group called NL Rising, which opposes the Liberal budget.
